Background: Few studies have reported on Barrett's esophagus (BE) in children. Moreover, information on the age at diagnosis and the duration between reflux-symptoms and diagnosis is lacking.
Methods: A review of the literature was performed in PubMed, EMBASE and the Cochrane database.
Results: Fourteen articles were included, of which 4 cohort studies and 10 studies investigating patients already diagnosed with BE. The cohort studies showed 37 patients diagnosed with BE (0.3-4.8%), mean age 12.4 years. Time between onset of reflux-symptoms and BE was 2.8 years. All 14 studies together showed 176 patients with BE (mean age 9.5 years). Time between onset of reflux-symptoms and BE was 5.3 years. During endoscopic follow-up of 45 patients, 26 still had BE, 17 no longer had evidence of BE, and two had developed esophageal-adenocarcinoma.
Conclusion: This review shows that BE and esophageal-adenocarcinoma occur in children. However, criteria used to define BE by the included studies were not comparable to the current criteria and data on GERD symptoms may have been inaccurate. Therefore, we recommend performing a long-term prospective study on the relationship between (duration of) GERD and the development of BE in children in order to define screening guidelines.

Background And Aims: We sought to develop a minimally-invasive, robust, accessible nonendoscopic strategy to diagnose Barrett's esophagus (BE), esophageal adenocarcinoma (EAC), and its immediate precursor lesion, high-grade dysplasia (HGD) based on methylated DNA biomarkers applied to a retrievable sponge-capsule device in a cohort representative of the BE population (i.e., mostly short-segment, non-dysplastic BE, NDBE).

Photodynamic therapy (PDT) is a treatment modality clinically approved for several oncologic indications, including esophageal and endobronchial cancers, precancerous conditions including Barrett's esophagus and actinic keratosis, and benign conditions like age-related macular degeneration. While it is currently clinically underused, PDT is an area of significant research interest. Because PDT relies on the absorption of light energy by intrinsic or administered absorbers, the dosimetric quantity of interest is the absorbed energy per unit mass of tissue, proportional to the fluence rate of light in tissue.

Background: In the UK's National Health Service (NHS), there is specific psychosocial care offered to people with genetic cancer risk conditions but not morphological cancer risk conditions. As researchers develop new ways to diagnose morphological risk conditions, including precancers and in situ cancers, it is important to consider the psychosocial care that those diagnosed might require.
Objectives: This study compares the National Institute for Health and Care Excellence's guidelines for BRCA1/2, which are genetic risk conditions, and Barrett's oesophagus (BO), a morphological risk condition.
Use of a Non-Endoscopic Capsule-Sponge Triage Test for Reflux Symptoms: Results From the NHS England Prospective Real-World Evaluation.

Department of Gastroenterology, East and North Hertfordshire NHS Trust, Hertfordshire, UK.
Background: Acid reflux is a common presentation in primary care leading to a high volume of referrals to endoscopy that are often normal.
Aims: To determine whether a non-endoscopic capsule sponge biomarker test could triage patients with low-risk reflux symptoms, reduce endoscopy waiting lists and identify Barrett's oesophagus in a real-world setting.
Methods: Patients with reflux symptoms on NHS endoscopy waiting lists who were offered a capsule sponge (test group) between February 2021 and August 2022 were included in this national multicentre prospective cohort study and compared with eligible patients on the standard endoscopy pathway (counterfactual group).
Histological features indicate the risk of progression of patients with Barrett's esophagus.

Our understanding of predictors of progression in Barrett's esophagus (BE) remains incomplete. To address this gap, we evaluated histological features and biomarkers that could predict dysplastic/neoplastic progression in patients with BE. We conducted a retrospective study to identify eligible BE patients and classified the cases into two groups: cases with BE progression (n = 10; progressing to high-grade dysplasia or carcinoma within five years of initial diagnosis) and cases without BE progression (n = 52; without progression to high-grade dysplasia or carcinoma within five years).
